Chapter 12, Problem 3E

Interpretation Introduction

Interpretation:

The liquid molecular models should be arranged according to the order of increasing viscosity at $25.0°C$

Concept introduction:

Viscosity of a liquid is the resistance to flow. The stronger the intermolecular forces, the greater viscosity. Hydrogen bonds are one of the intermolecular forces, in which hydrogen atom covalently bonded to a highly electronegative atom gets attract to the neighboring electronegative atom. Alcohols are compounds that contain hydroxyl group or groups (-OH) to an alkane group (carbon and hydrogen single bonded group). They show hydrogen bonding between H atom in the hydroxyl group of 1 alcohol and O atom of the other hydroxyl group.
